Background
Because the jaw bone of children grows the not mature physiological characteristics and is in the psychological behaviour characteristics of young, children are injured in playing, motion process easily, when jaw facial portion receives external force impact or because of falling down and striking ground and take place jaw injury, the jaw bone fracture is comparatively common. The condylar fracture accounts for 24% -72% of the mandibular fracture, and often causes facial deviation and dysfunction of the infant after the fracture occurs, and seriously affects the physical and mental health of the infant. After the condylar fracture of the child, the occlusal muscles pull the mandible and dentition of the affected side, and the height of the mandible of the affected side may be reduced and the mandible may be reversely closed. The existing combined cushion has uniform thickness, can not open the affected side and the healthy side to different occlusion heights, and can not effectively recover the position of the fracture broken end; the retention of the common occlusion cushion is not good, and the protrusion position of the lower jaw cannot be effectively determined due to the lack of the occlusion cushion effect between the upper jaw and the lower jaw, so that the lower jaw cannot be stabilized; the teeth are fixed by the snap ring and the gap clamping hook, but as the clinical crowns of the deciduous teeth and the children patients in the tooth replacement period are short, permanent teeth are not erupted yet, the retention force is weak, the occlusion movement is carried out when the patients chew, the chewing muscle strength is large, and the dislocation of the composite pad is more easily caused; the occlusion function is recovered and the function of guiding the lower jaw to extend forward is not good because the occlusion relation is not matched with the relation of the involutive tooth cusp and the fossa.
